The screening of patient urine samples for basic drugs is typically performed following a lengthy sample preparation methodology that requires a time consuming dry down step. A novel elution protocol coupled to the EVOLUTE EXPRESS advanced plate technology affords a fast sample preparation solution that follows a LOAD-WASH-ELUTE-ANALYZE strategy. Basic drugs are fortified into urine and extracted in 3 easy steps using EVOLUTE EXPRESS CX solid phase extraction in a 96-well plate format.

This report details a “load, wash, elute” weak cation exchange solid phase extraction procedure amenable to both plasma and urine samples. The extracts are subsequently injected into an LC-MS/MS system. The preliminary sample preparation method was developed at the Biotage US Applications lab (Charlotte, NC).The method was then transferred to Ionics (Bolton, ON, Canada) to facilitate the nmole/L measurements of the selected biomarkers by laminar flow tandem mass spectrometry. The SPE-LC-ESIMS/ MS method parameters were first optimized using pooled mixed gender plasma. A set of patient samples (n=32) was later supplied by the Mayo Clinic (Rochester, MN) that had previously been analyzed by a validated referee method. The population represented measured values across a range of clinical relevance. AACC 2014

This poster describes a reduced workflow solid phase extraction method for extraction of vitamin B7 (biotin) from human serum. Using EVOLUTE EXPRESS AX 96-well plates, the traditional sorbent conditioning and equilibration steps are not required, meaning the sample can be applied directly to the dry plate. Post extraction evaporation is also eliminated. ASMS 2014

In this poster, an IONICS 3Q 220 triple quadrupole mass spectrometer using a load, wash, elute method protocol with recently advanced solid phase extraction (SPE) sorbent technology (EVOLUTE EXPRESS WCX) was used to perform analysis of the two compounds. As a result low levels of metanephrine and normetanephrine are detectable in plasma with short sample preparation and LC run times. This LC-MS/MS method provides a fast, sensitive, accurate, and reproducible solution for the analysis of ME and NME in plasma. MSACL 2014

EXPRESS represents a leap forward in high throughput solid phase extraction. The EVOLUTE EXPRESS range of 96-well SPE plates combines powerful EVOLUTE sorbent chemistry with innovative features that enhance productivity by optimizing or even eliminating the need for some traditional steps in the SPE procedure. By truly eliminating the need for conditioning and equilibration, samples can be prepared by loading the plate, washing away interferences and eluting with compatible solvents
